Abstract
A data storage apparatus may include a storage and a controller configured to operate in a throttling mode including a first performance mode and a second performance mode based on measured temperature of the storage. The controller comprises a performance adjusting component configured to determine target performance of the first performance mode based on at least one of temperature of the storage and the number of entries into the second performance mode when the temperature of the storage is greater than or equal to a first threshold value.
Claims17
A data storage apparatus comprising:
- a storage configured to store data;
- and
- a controller configured to exchange data with the storage in response to a request of a host and to operate in a throttling mode including a first performance mode and a second performance mode based on measured temperature of the storage,
- wherein the controller comprises:
- a performance adjusting component configured to determine target performance of the first performance mode based on temperature of the storage and the number of entries into the second performance mode when the temperature of the storage is greater than or equal to a first threshold value.
A data storage apparatus comprising:
- a storage configured to store data;
- and
- a controller configured to exchange data with the storage in response to a request of a host, and to operate in a throttling mode including a first performance mode and a second performance mode based on measured temperature measurement of the storage,
- wherein the controller is configured to determine target performance of the first performance mode based on history of entry into the throttling mode, and
- wherein the history of entry into the throttling mode includes the number of entries into the second performance mode which is a lower performance mode than the first performance mode.
An operation method of a data storage apparatus including a storage configured to store data and a controller configured to exchange data with the storage in response to a request of a host, the operation method comprising:
- determining, by the controller, whether to enter a throttling mode including a first performance mode and a second performance mode based on measured temperature of the storage;
- comparing, by the controller, the temperature with a first threshold value;
- and
- determining, by the controller, target performance of the first performance mode based on the temperature of the storage and the number of entries into the second performance mode when the temperature of the storage is greater than or equal to the first threshold value.
A data storage apparatus comprising:
- a storage including a temperature sensor;
- and
- a controller suitable for:
- receiving, from the storage, a signal indicative of the temperature of the storage;
- controlling the storage to operate in a first temperature throttling mode such that the data storage apparatus operates at a first percentage of maximum performance when the temperature of the storage is greater than or equal to a first threshold value;
- controlling the storage to operate in a second temperature throttling mode such that the data storage apparatus operates at a second percentage of maximum performance when the temperature of the storage is greater than or equal to a second threshold value, which is greater than the first threshold value,
- wherein the first percentage is adjusted based on the number of entries into the second temperature throttling mode.
